Astigmatic change after myopic spherical excimer PRK.
85 Patients who underwent a spherical PRK with an average of 6.08 dptr. and who could be followed over a period of 1 year were evaluated. After 1 year an average induced astigmatism of 0.58 dptr. was found. There seems to be a correlation between induced astigmatism and depth of PRK but not between induced astigmatism and pre-existent astigmatism. In cases of decentrated PRK a spontaneous regression of laser-induced astigmatism could be observed.
